Definitions
- the present invention relates the non-therapeutic use of strobilurin type compounds of formula I and the N-oxides and the salts thereof for combating phytopathogenic fungi containing an amino acid substitution F129L in the mitochondrial cytochrome b protein (also referred to as F129L mutation in the mitochondrial cytochrome b gene) conferring resistance to Qo inhibitors (Qol), and to non-therapeutic methods for combating such fungi.
- the invention also relates to novel compounds, processes for preparing these compounds, to compositions comprising at least one such compound, to plant health applications, and to seeds coated with at least one such compound.
- the present invention also relates to a non-therapeutic method for controlling soybean rust fungi ( Phakopsora pachyrhizi ) with the amino acid substitution F129L in the mitochondrial cytochrome b protein.
- Qo inhibitor includes any substance that is capable of diminishing and/or inhibiting respiration by binding to a ubihydroquinone oxidation center of a cytochrome bc 1 complex in mitochondria.
- the oxidation center is typically located on the outer side of the inner mitochrondrial membrane.
- Many of these compounds are also known as strobilurin-type or strobilurin analogue compounds.
- the mutation F129L in the mitochondrial cytochrome b (CYTB) gene shall mean any substitution of nucleotides of codon 129 encoding "F" (phenylalanine; e.g. TTT or TTC) that leads to a codon encoding "L" (leucine; e.g. TTA, TTG, TTG, CTT, CTC, CTA or CTG), for example the substitution of the first nucleotide of codon 129 'T' to 'C' (TTT to CTT), in the CYTB (cytochrome b) gene resulting in a single amino acid substitution in the position 129 from F to L in the cytochrome b protein.
- Such F129L mutation is known to confer resistance to Qo inhibitors.
- Qol fungicides often referred to as strobilurin-type fungicides ( Sauter 2007: Chapter 13.2. Strobilurins and other complex Ill inhibitors. In: Krämer, W.; Schirmer, U. (Ed.) - Modern Crop Protection Compounds. Volume 2. Wiley-VCH Verlag 457-495 ), are conventionally used to control a number of fungal pathogens in crops.
- Qo inhibitors typically work by inhibiting respiration by binding to a ubihydroquinone oxidation center of a cytochrome bc 1 complex (electron transport complex III) in mitochondria. Said oxidation center is located on the outer side of the inner mitochrondrial membrane.
- a prime example of the use of Qols includes the use of, for example, strobilurins on wheat for the control of Septoria tritici (also known as Mycosphaerella graminicola), which is the cause of wheat leaf blotch.
- Septoria tritici also known as Mycosphaerella graminicola
- widespread use of such Qols has resulted in the selection of mutant pathogens which are resistant to such Qols ( Gisi et al., Pest Manag Sci 56, 833-841, (2000 )).
- Resistance to Qols has been detected in several phytopathogenic fungi such as Blumeria graminis, Mycosphaerella fijiensis, Pseudoperonspora cubensis or Venturia inaequalis.
- soybean rust acquired a different genetic mutation in the cytochrome b gene causing a single amino acid substitution F129L which also confers resistance against Qol fungicides.
- the efficacy of Qol fungicides used against soybean rust conventionally, i.e. pyraclostrobin, azoxystrobin, picoxystrobin, orysastrobin, dimoxystrobin and metominostrobin, has decreased to a level with practical problems for agricultural practice (e.g. Klosowski et al (2016) Pest Manag Sci 72, 1211-1215 ).
- trifloxystrobin was less affected by the F129L amino acid substitution to the same degree as other Qol fungicides such as azoxystrobin and pyraclostrobin, trifloxystrobin was never as efficacious on a fungal population bearing the F129L Qol resistance mutation as on a sensitive population ( Crop Protection 27, (2008) 427-435 ).
- WO 2017/157923 discloses the use of the tetrazole compound 1-[2-[[1-(4-chlorophenyl)-pyrazol-3-yl]oxymethyl]-3-methylphenyl]-4-methyltetrazol-5-one for combating phytopathogenic fungi containing said F129L amino acid substitution.
- new methods are desirable for controlling pathogen induced diseases in crops comprising plants subjected to pathogens containing a F129L amino acid substitution in the mitochondrial cytochrome b protein conferring resistance to Qo inhibitors.
- the fungicidal activity of the known fungicidal strobilurin compounds is unsatisfactory, especially in case that a high proportion of the fungal pathogens contain a mutation in the mitochondrial cytochrome b gene conferring resistance to Qo inhibitors.
- new fungicidally active compounds which are more effective, less toxic and/or environmentally safer. Based on this, it was also an object of the present invention to provide compounds having improved activity and/or a broader activity spectrum against phytopathogenic fungi and/or even further reduced toxicity against non target organisms such as vertebrates and invertebrates.
- the strobilurin-analogue compounds used to combat phytopathogenic fungi containing a F129L amino acid substitution in the mitochondrial cytochrome b protein conferring resistance to Qo inhibitors according to the present invention differ from trifloxystrobin inter alia by containing a specific group attached to the central phenyl ring in ortho position to the side chain defined herein as R 3 .
- the mutation F129L in the cytochrome b (cytb, also referred to as cob) gene shall mean any substitution of nucleotides of codon 129 encoding "F” (phenylalanine; e.g. TTT or TTC) that leads to a codon encoding "L” (leucine; e.g.
- TTA, TTG, TTG, CTT, CTC, CTA or CTG for example the substitution of the first nucleotide of codon 129 'T' to 'C' (TTT to CTT), in the cytochrome b gene resulting in a single amino acid substitution in the position 129 from F (phenylalanine) to L (leucine) (F129L) in the cytochrome b protein (Cytb).
- the mutation F129L in the cytochrome b gene shall be understood to be a single amino acid substitution in the position 129 from F (phenylalanine) to L (leucine) (F129L) in the cytochrome b protein.
- phytopathogenic fungi acquired the F129L mutation in the cytochrome b gene conferring resistance to Qo inhibitors, such as rusts, in particular soybean rust ( Phakopsora pachyrhizi and Phakopsora meibromiae ) as well as fungi from the genera Alternaria, Pyrenophora and Rhizoctonia.
- rusts in particular soybean rust ( Phakopsora pachyrhizi and Phakopsora meibromiae ) as well as fungi from the genera Alternaria, Pyrenophora and Rhizoctonia.
- Preferred fungal species are Alternaria solani, Phakopsora pachyrhizi, Phakopsora meibromiae, Pyrenophora teres, Pyrenophora tritici-repentis and Rhizoctonia solani; in particular Phakopsora pachyrhizi.
- the present invention relates to the method of protecting plants susceptible to and/or under attack by phytopathogenic fungi containing an amino acid substitution F129L in the mitochondrial cytochrome b protein conferring resistance to Qo inhibitors, which method comprises applying to said plants, treating plant propagation material of said plants with, and/or applying to said phytopathogenic fungi, at least one compound of formula I or a composition comprising at least one compound of formula I.
- the method for combating phytopathogenic fungi comprises: a) identifying the phytopathogenic fungi containing an amino acid substitution F129L in the mitochondrial cytochrome b protein conferring resistance to Qo inhibitors, or the materials, plants, the soil or seeds that are at risk of being diseased from phytopathogenic fungi as defined herein, and b) treating said fungi or the materials, plants, the soil or plant propagation material with an effective amount of at least one compound of formula I, or a composition comprising it thereof.
- the term "phytopathogenic fungi an amino acid substitution F129L in the mitochondrial cytochrome b protein conferring resistance to Qo inhibitors” is to be understood that at least 10% of the fungal isolates to be controlled contain a such F129L substitution in the mitochondrial cytochrome b protein conferring resistance to Qo inhibitors, preferably at least 30%, more preferably at least 50%, even more preferably at at least 75% of the fungi, most preferably between 90 and 100%; in particular between 95 and 100%.
